1 Data exploration

1.1 Players

The total sample includes 95 participants.
The total number of games played is 301.
ADHD is defined as ADHD_score < 5 (i.e., CTL is ADHD_score > 4).

1.1.3 Number of games played (by one participant)

Participants played between 1 and 144 games.

1.1.4 Last positions

Most participants completed the 3 minutes (180 sec). Very few stopped before the end.

1.1.5 Table with dates and butterflies found

1.2 Correlations

1.2.1 correlations between subject variables

shall we focus on participants who complete the game (i.e., TiemOfLastPosition == 179)?

1.2.2 correlogram between time and positions

1.2.3 correlogram between number and time

1.2.4 scatterplot matrix

2 Data from 1 participant

an interactive version of this plot is available which allows to select 1 (or more) players to visualize their data.

3 Group data: ADHD vs controls

ADHD are defined as ADHD_score < 5.
Raw (unfiltered) data is used.

3.1 mean collection times

3.2 number of butterflies found

Main effect of group

Main effect of age The effect of age is significant in ADHD group but not controls.
The median age is 8 years old. The effect of group is significant in younger participants (mean age 7.49 yo) but not in older participants (mean age 9.49 yo).

post hoc contrasts.
